LOCOMQTIVE.

To all whom t 'may concern.'

Be it known that I, WILLIAM W; SLOANE, a citizen of the United States, residing at Chicago, in the county otCook and State of Illinois, have invented an Improvement in Locomotives, of which the following vis a specification.

This invention relates to improvements in locomotives or trucks and has tor its principal object to provide an improved construction aiording relative flexibility of the supporting wheels and axles so as to readily follow uneven track.

A usual type vof construction` ot locomotives comprises a plurality oi" axles with supporting wheels thereon, said axles jour naled in suitable axis boxes mounted in vertically disposed `guides carried by the locomotive't'rame and having springs interposed between each axle box, andthe frame. Such a construction allows the ends of an axle to move vertically a limited distance, depend ing upon the resiliency of the springs, thereby affording limiting flexibility ot movement of opposite ends of the axle.

In the present invention I providetransversely movable means aiording greater flexibility of movement of the axle, com- .;prising an equalizing device in which the opposite ends Otan axle have a pair of bell crank levers interposed between them and the frame. The bell crank levers are operatively connected with each other, so as to allow the axle to Swingin a vertical'plane independent of the resiliency of the springs.

This invention consists in the combination, construction and arrangement of parts as will hereinafter be described in connection with the accompanying drawings and more particularly defined in the appended claims.

Figure l is a fragmentary top plan view of one type of locomotive constructed in accordance with my invention.

Figure 2 is a vertical cross section taken on line v2--2 of Figurey l with a portion of a supportingwheel lbrokenfaway to show the mounting'for one end of the axle.

Figure 3 is an enlarged transverse cross section taken Online 3-3' of Figure 1.

Figure 4 is a view similar to Figure 2 showing an alternative form of my invention.

` Figure '5 is a. vertical cross section taken on line 5-5 of Figure 4.

Figure 6 is a side view illustrating the manner ot` applying my improved construction to a two-axle locomotive.

Figure 7 is aside view of a three-axle locomotive, illustrating another application of my invention.

Figure 8 is a side view of a four-axle locomotive illustrating a third manner in which my invention may be applied.

In the drawings, a simple embodiment ot my invention is lshown as applied to the locomotive shown in Figure 6. A portion of this locomotive is shown in Figures l, 2 and 3, in which appear two side plates 2, 2, constituting the main portion ot the frame, an

axle 3, and a pair ot supporting wheels e, 4t, thereon. A motor'casingp is suspended on the axle 3 to provide motive power therefor, said motor casing being iournaled at one end on the shaft 3 and flexibly connected near the other end to the locomotive trame in any manner suitable to electric locomotives ot the type illustrated.v Each end of the axle 3 is journaled in ajournal box 6 ot any approved construction, said journal box being arranged to move vertically between pedestals, or guide plates 7, 7 of` the usual Construction.

Referring now more particularly to the novel features constituting my invention, the locomotive frame is supported on the journal boxes 6, 6 through the medium of an equalizing device constructed as follows: In the embodiment of my invention illustrated in Figures l, 2 and 3, a pair of rocking members 8, 8 are mounted on the locomotive` frame above their respective axle boxes. Each of said rocking members comprises, in effect, a bell crank lever pivotallymounted to swing in a vertical plane transversely of the locomotive.

In the form illustrated, said rocking member has two bearing pins 9, 9, on a common longitudinal axis and pivotally mounted in brackets l0, l0, carried on the side plate 2 of the locomotive frame. Said pins form the fixed axis of movement of the rocking member and are connected together by a longitudinally extending member l1.- One lever arm of the rocking member comprises an arm l2, (see Figures 2 and 3) connected to the longitudinal memberll and arranged to one side of the axis of pivot pins 9, 9. `Said member 12 bears on a stirrup 13, which Cfr .longitudinal member 11a. In

Figure 3, to iit '1n a corresponding depres-l sion 15 formed in the upper surface of said stirrup. The parts are retained in place by a pair of pins 16, 16, extending through opposite ends of the stirrup, and into recesses in the arm 12 as shown.

The second lever arm of therocking member 8 comprises an inwardly extending mem- Vber 17, arranged above 'the axis of said roclring member and pivotally connected with a transverse equalizing bar 18, extending across the locomotive and attached to a similar rocking arm above the opposite end of 'the axle 3.

In applying my invention to a locomotive of the twofaxle type shown in Figure 6,one supporting axle 3a' is preferably mounted in e the usual manner, that :is to say, without an equalizing device, so as to provide a desired stability to the frame, while the other supporting axle is mounted as abovedescribed,

so as to afford a wide range of flexibility withrespect to the frame and the one stabilizing axle `connected therewtih as described. By means of this arrangement, the

locomotive wheels may readily follow uneven track.

'Among other forms in which my invention may be embodied, I have illustrated a .modification in Figures 4: and 5, which is particularly adapted for use in instances 'where' the overall height of the locomotive is limited, as for instance, in a mine locomotive. In this construction, the longitudinally extending member 11, corresponding with the member 11 in the preferred construction, is lengthened considerably to accommodate the supporting wheel 4a, the up- 4 per flange of which extends vertically above thel axis of the supporting pivots 9a, 9a, as clearly shown in Figure 5. Also, the crossbar 17? is positioned near one end of the other respects the construction and operation isy similar to the form already described.

Inthe form illustrated in Figure rn invention is shown-as applied to a threeaxle llocomotive having a pairof equalizer 'bars 30, 30 of the usual type at each side of my device the frame. Each equalizer -bar extends from `the center axle-box to an end axle-box and has a suitable setof 'springs 31 interposed between said bar'and the locomotive frame.v In order to provide transverse equalization Vwith my device, the springs 31 at one end, l'of the frame are cross-connected by an equalizing device similar to that shown in Figures 1,

2`and 3. e Another application of' is shown in Figure 8 which shows a four-axle locomotive Vin `which the axleslv are grouped impairs, each pair having lon-l lcomprising a pair ofrocking members, each pivotally mountedvon opposite'sides of the frame and affording a vertically movable 'support orone end oi said axle, and horirocking lmembers together.

2. In a car, a frame, an axle having supporting wheels, journal boxes adjacent the ends of said axle, guide means on said frame permitting` limited verticalv movement of zontally movable 'means connecting said said journal'boxes, andan equalizing device 'comprising two bell crank levers, each pivotal y mounted on the frame and having a laterally disposed arm in supporting relation with onexjournal box and a substanm tially vertical arm, and means operatively connecting-said vertical arms together.

3. In a car, a` frame, av pair of laterally spaced axles, one fof said axles being provided with a transverse equalizing device comprising a pair of rocking members each pivotally mounted on opposite sides of the frame, and laiiordinga vertically movable support for oneend of` said equalized axle, and horizontally .movable means `connecting said rocking members together.`
